! To all whom it may concern:

Be it known that I, WILLIAM H. ScHUY- LER, a citizen ofthe United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Space-Band Cleanto the bands.

ers, of which the following is a description.

My invention relates to that'general class of devices known as space-band cleaners employed for preparing the space-bands employed upon linotype machines or the like, for use in the linotype machines. The invention herein described is an improvement on the space-band cleaner shown in my. U. S. Patent No. 914,522, granted March 9,1909. The invention has among its objects the pro duction of a device of the kind described that is simple, strong, durable, compact,,efficient and satisfactory, for use Wherever found applicable. It has particularly as an object the production of an automatic device of the kind described for cleaning and coating or graphiting space-bands, and which operate rap-idly with a minimum of labor, doing better and more work. in less time and with less labor than where the same is done with other machines or by hand. It also has as an object the production of a machine which will remove any type metal composition or the like adhering It 'has in addition to the objects above set forth the production of a machine which, while rapid in operation, will actually do more cleaning and coating on each space-band in the same time than other machines. It takes a set of space bands as taken out from the linotype machines, and feeds the bands successively through the machine, discharging them all arranged so that the set may be removed from my machine in its entirety and used in the linotype machine without re-arranging them. Many other objects and advantages of the construction hereindescribed will be obvious to those skilled in the art from the disclosure herein made.

To this end my invention consists in the novel construction, arrangement and combination of parts herein'shown and described, and more particularly pointed out in the claims. 7

may be said, however,.that after a certain amount of use of the bands in the linotype machine, it is found desirable to. clean the bands and coat the faces of .the same, particularly oneface with a finely powdered graphite or other suitable material, so as to prevent as far as possible the adherence of thetype metal to the bands, and facilitate the use of the bands. Insome cases, particularly at the point X, marked on the space-band shown in the drawings, a portion of the type metal often adheres to the band. In the ordinary method of cleaning bands by hand or otherwise this adhering metal i snot entirely removed, and in some cases not removed atall, but with my improved type of machine herein described, any type metal which does adhere to the space-band is automatically cut ofl during its passage through my cleaner. My improved machine .in its broadest sense consists of a suitable space-band support or carrier, means for cleaning and. coating the band, means for maintaining the band and cleaning and coatingmeans inclose contact, together with mechanism, for receiving and assembling the cleaned bands, and suitable driving mechanism. p y

In order to make clear the purpose, construction and. operation of my device, I have illustrated in Fig. 10 one of the space-bands for the cleaning of which the machine is intended. As shown in the above figure, 3 represents a portion of the space-band, which carries a slide having a face 4, the slide being ordinarily provided with shoulders 55, and the same is substantially of the appearance shown, and is open in the center or slotted. The face 4 is the one that it is ordinarily desired to clean, and it is on this face and at substantially the point marked X that there is frequently a tendency for the type metal to accumulate. These space-bands usually are in sets of thirty, and may be taken from the linotype machine substantially as a complete set at one time. In placing them in the machine they are also handled substantially as a set. Heretofore it has been customary when the bands were cleaned by hand, to take each band and rub the face 4 on a suitable surface so as to coat the same with graphite or other suitable material, substantially lubricating it and preventing the adhesion of type metal thereto. They are then assembled in the set and returned to the linotype machine as desired.

My improvement consists of a suitable frame 1, provided with a base 2, or the equivalent, for supporting the same. Carried by the frame is a rubbing member, which in the preferred construction consists of a rotatable wheel 9, formed with a suitable face plate 10, the flat face of the wheel being used for rubbing, or as the rubbing face. The wheel 9 is carried by a shaft 11 extending through a bracket 12, the same being locked in place by the collar 13, or equivalent means. The rubbing wheel shown is driven by a bevel gear pinion 14, which meshes with a pinion 1.5, carried on shaft 16, the shaft 16 extending through the part 17 which is in the form of a sleeve and carries bracket 12. The sleeve 17 is carried by the part 18, on the back of the frame (see Fig. 3), the same being prevented from displacement by colllar 19, or equivalent means for the purpose. On the outer end of shaft 16 is arranged a gear 20, which meshes with gear 21, arranged on the driving shaft The driving shaft 22 may be driven in any desired manner, as for example by a pulley 23, which is in turn driven through belting or other connecting means by any suitable power. As was previously mentioned, my invention is intended to clean and coat the face 4 of the band with graphite. or equivalent material. This is preferably done by first coating the rubbing wheel face 10. In coating the face of the rubbing wheel, I have shown a graphite receptacle formed within the frame, preferably having a sloping bottom 24, so that when the chamber is filled with graphite the same will feed down to the face of the wheel, a portion of the wheel substantially projecting into the graphite chamber. If desired,

'44, to which is Secured shaft 45.

wheel serves substantially as an arm on the a cover 25, or its equivalent, may be provided for the top of the graphite chamber. It is, of course, understood that the wheel or rubbing member may beconstructed of any desired material and be of any suitable shape. In the construction shown part 9 is of metal and the part 10 of fiber. I have shown recesses, or holes 26 in the face of the fiber plate 10, (see Fig. 2) the purpose of these being that they tend to accummulate graphite and carry the same with the wheel. I have found in practice, however, they may be omitted apparently without impairing the efiiciency of the machine to any eX- tent.

The bands are cleaned and coated with graphite in the machine illustrated by moving the same over the flat face of the rotating rubbing wheel. In the construction as shown the bands are successively fed to a carrier, which carries them into contact with the rubbing member, and after being coated, they are automatically discharged and collected. The carrier shown comprises a mem ber 30, which extends through slot 32 in the frame, and is provided with flanges 31 (see Figs. 1 and 2) or the equivalent. The same is slidably secured in place by the guides 33, which clamp the flanges 31 between the guides and portion of the frame. The carrier is formed with two projecting parts 34, with a space 35 between the same. At the ends of the extensions 34 are provided shoulders 36, (see Fig. 8) which are adapted to engage with the shoulders 5 on the band and lift the same to the rubbing member. The same may also be slightly cut away so as to clear the upper portion of the bands, the space 35 bein but slightly larger than the width of the ands. I have also shown a guide 3S39, carried by the part 40. This serves to guide and steady the upper portion of the carrier so that the band will move with its face substantially close to the rubbing wheel.

The carrier may be operated in any desired manner, the same having a reciprocable vertical movement. For the purpose I have shown a link 41, having one end pivotally secured to the carrier stud 42, and the other end pivotally secured at 43 to a gear wheel The gear shaft, and in addition constitutes a convenient method of driving the shaft. As shown, gear 44 meshes with the small pinion 46 arranged on shaft 47 which shaft is driven by the gear 48 secured thereto, and which meshes with a gear 49 carried by the driving shaft 22, the driving shaft being driven as previously described.

Carried by part 40, and preferably be- 52, and secured to part 40' in any suitable manner. As shown, a screw is provided for this purpose, the part 52 being adjustably secured to part 40. Part, 51 is recessed and formed with a cutting edge at 54, the purpose of this cutting edge being to shave the face 4 of the band, and if there is any type metal at the point marked X, to cut the same ofi".

Any suitable means may be provided for feeding the bands tothe carrier. As shown, I have provided'a very simple feeding device, which may be of suflicient size to carry the desired number of bands. This consists of the part 40 previously referred to, which is extended as at 53, the outer end of the same being open at the top, as shown in Fig. 3, for convenience in placing the bands, if the same is desired. The part 40 and extended part 53 are flanged as at 55 to form a runway or slide face 55 at each side. These are so proportioned as to engage the shoulders 5 on the bands and slidably carry the same. The same are shown inclined so that the bands feed by fl lgravity, the weight of the bands being su cient to cause the band adjacent the carrier to be picked up and carried ordinarily at each upward movement of the same. The parts, of course, are so proportioned that only one band is picked up at a time. I have also shown a guide 53 arranged to enter the notch in the end of the sliding plate on the band, this serving to prevent the bands from turning and becoming cramped on the faces 55. If desired, a guide 52 may be arranged for the lower ends of the bands, this serving to prevent their tipping orrocking on the faces 55'.

While ordinarily the carrier tends to maintain the band face 4 in close contact with the rubbing member or wheel, I prefer to provide supplemental means which will tend to hold the face 4 parallel and in close contact with the rubbing wheel. This permits the parts to be so proportioned that the'bands do not have to be firmly held in place or locked on the carrier. For the purpose I have shown a retaining member or plunger 56, whichis shown formed with a shank 57 projecting into part 58 of a reciproeating carriage 59. The reciprocating carriage for the plunger substantially consists of the carriage part 59 slidable on the guide 60, the movement of the same, however, being limited by the stops 61 and 62. The plunger is reciprocable relative its carrier, and as shown is formed with a shank 63, about which is arranged a spring 64:, the spring tending to normally force the plunger toward'the rubbing wheel. The plunger, as a matter of fact, has two movements, that is it is movable in a direction toward or away from the rubbing wheel, and 'transversely with the band carriert When the band carrier: is at the extreme end. of its downward travel the plunger carrier is substantially as indicated in Fig. 1, and remains there untilthe band is carried up to the plunger, at which time the plunger contacts with the band and moves upwardly with it, maintaining the same in close Contact with the rubbing wheel. The same then follows the band back to a certain point, and thereafter releases the band, as will be hereafter described in the operation of the device. The plunger and its carrier are normally moved upwardly by the band carrier, and while its control is .controlled bythe band carrier, it is preferably independently retrieved by the spring 65, or equivalent means. As shown, spring 65 is secured .at 66 to the frame at one end, and at. its other end to a rod 67, secured to the plunger carriage. Any equivalent retrieving means may be provided for this purpose.

Iteferring to Figs. 1, 2 and 3, the band carrier 30 is provided with a flange 69", whichis formed with a cam face 70. The cam face 70-is adapted to co act with a roller 71' arranged on the stud 72 on the plunger. The. stud is guided by the guides 73. .The member, 69 also carries apin or lug74, arranged to co-act with an extension which is secured to, or forms a part ofthe carrier 59. The cam face 70 and face 40 and roller coeperating forces and maintains. the plunger 56 back, as indicated in Fig. 1. While pin 74 and extension 75 cotiperate to raise the plunger carriage and. control itsreturn, the spring 65 drawing it back as the band carriage carriermoves downwardly. I

To receive and assemble the cleaned bands, I providev an arm or finger 78, which iscarried by the extension 77 on the frame in any suitable manner. As shown, finger 78 is formedwith an end 80, which is pivotally secured in the rocking stud 79, by the pin 81. The shaft 7 9 has a slight rocking move ment, the movement being limited by the pinS l', working the slot 85. The movement of the finger 78 about its pivot 81 is to a certain extent controlled by the pin 82,actuated by the spring 83'. As most clearly shown in Fig. 9, when the finger is turned back to operative position shown in Fig. 1, the pin 82 yieldingly maintains thei'same in place.

The pressure of the spring, however, may be easily overcome and the finger. swung about its pivot pin 81 when it is desired to remove the assembled bands from the finger 78. As most clearly shown in Figs. 2, and 8 a recess 87 is provided in the part 4.0, the same being arranged to receive'the free end of finger 7 8'.

The finger'78-is actuated or controlled during certain-movements of the band carrier by the leg or extension 88, this serving to lift the end of the finger in the manner here after described.

The operation of the machine is substantially as follows: Referring: particularly. to

Figs. 1, 7 and 8, the space bands are hung from the extensions 55, the shoulders 55 resting upon thefaces 55. Assuming that the carrier for the bands is at th lower end of its travel, and in position to receive a new spacing band. The finger 78 and plunger 56 and lunger carriage 59 are substantially as shown in Fig. 1. Assuming that shaft 22 is drivenin any suitable manner, thereby driving the rubbing wheel through the intermediate gearing referred to, and driving the wheel 44 through the gearing connected therewith, as previously mentioned. This drives the wheel 44, as indicated by the arrow in Fig. 1, and as the same rotates the band carrier 30 is lifted by means of the link 44 to the extreme upper limit of its travel (see Fig. 7, full lines). As the same moves upwardly it carries the adjacent space-band, the shoulders 55 of the same resting on the shoulders 3636 of the carrier. The plunger 56 is maintained substantially as shown in Fig. l by the face bearing against the roller 71. As soon as the band carrier has raised a certain distance, however, roller 71 co-acting with the cam face 70, ermits the plunger to move toward the band, and bear against the same. As the same bears against the band, pin 74 engages extension 75, carrying the plunger and its carriage upwardly with and at the same rate of travel as the space-band and its carrier. The plunger, however, maintains the space-band face 4 in close contact with the knife edge 54, and thereafter with the face of the rubbing member or wheel. As the same moves upwardly the rubbing wheel 9 bears on the band face 4, thoroughly cleaning and graphiting the same, (see Fig. 7 It will be noted that the plate has a flat bearing of considerable area on the space-band, and that by virtue of the link movement at the time the upper end of link 41 is passing the center, the space-band face is substantially stationary on the rubbing member. The graphite on the rubbing wheel or member is replenished from the graphite reservoir or receptacle as required. After the upper end of link 41 has passed the center and moves downwardly toward the position indicated in Fig. 1, the spring 65 tends to draw the plunger carriage 59 downwardly with the band carrier. The downward movement, however, is controlled and retarded by the pin 7 4 and extension 75 until the carriage reaches its stop 61, at which time the carriage stops and the pin 74 moves downwardly, being carried on by the member 69 and band carrier. The roller 71, however, still allows th band to remain in contact with the rubbing wheel and part 40 until the cam face 70 acts on the roller 71, as indicated in the dotted lines in Fig. 7. The band carrier, however, moves downwardly while the band supported by the plunger holds the same against the wheel and adjacent parts.

During the upward movement of the band carrier and plunger carriage, the finger 78 is moved from the position indicated in Fig. 1 to the position shown in Fig. 7, the same supported and controlled by the lug 88 when the carrier has passed a certain upward point, and until a certain amount of its return. The finger therefor does not bear against the band or carrier. As the carrier 30 drops, however, finger 78 drops, as indicated in the dotted lines in the figure mentioned, the free end resting in the recess 87. It will 'be noted, however, that the finger now extends through the space or slot in the band. As soon as the cam face 70 co-acts with the roller 71, and plunger 56 is retracted, and the band carrier drops to the position indicated in Fig. 8, the band being supported by the finger 78. The upper end, however, bears against the plunger, while the lower end is still in engagement with the carrier 30. As the carrier 30 moves farther down, however, the lower end of the band being released, the band flips out substantially as indicated in the dotted lines in the above figure (Fig. 8), and rides down the finger to the lower end, substantially as indicated in Fig. 1. After all the bands in the machine are cleaned, finger 78 may be slightly raised and then swung on the pin 81 and the assembled bands removed. 'The arm or finger 78 may then be turned back to the operative position shown in Fig. 1. The operations may then be continued on other sets as long as required.

By constructing the feeding and receiving mechanism with the guides 55 at an angle or inclination, and the finger 78 at an inclination, the feeding and assembling of the bands is affected by gravity. By employing a wheel or rubbing member of the type described, and forcing or maintaining the band in contact with the fiat face of the rubbing wheel, it will be observed that I have an extremely large bearing face working on the plate face. Also by employing the link construction at the upward travel of the carrier 30, there is substantially a slight rest or hesitation of the carrier before starting its downward movement, during which time the band is thoroughly cleaned. The cleaning time is therefore materially increased without impairing the capacity or increas ing the total time required to clean a set. I have found by experiment that it is not essential that the carrier travel vertically nor the plunger horizontally, as if the machine shown and described is tilted in one direction orthe other, the results are substantially the same. It will be noted that the pressure exerted by the plate on the rubbing wheel may be varied by changing spring 64, or in an equivalent manner.

Likewise, the speed of the various parts relative to each other may be modified by changing the various gear ratios, but I have found that the ratios now employed as illustrated in the drawings give very satisfactory results. Therefore while I have stated in a portion of the claims that the band carrier is vertically movable and the plunger horizontally movable, I wish to be understood that this is more particularly intended to bring out the relative travels or movements of the carrier plunger and rubbing member,'the essential features being a suitable rubbing member, which is preferably movable, the band carrier and rubbing mem- V ber being also relatively movable, it being immaterial which one is moved relative the other, and a retaining member of suitable form which will retain the plate and rubbing member in contact.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without dearting from the spirit of my invention; ence I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described, or uses mentioned.
